Project Summary

The primary goal of this project is to develop a wireless power transfer device. Based on this concept, the project is intended to transfer power over a short distance. A Wireless Power Transfer (WPT) is the process of transmitting electrical energy across an air gap from a power source to an electrical load using induction coils. These coils produce an electromagnetic field that transmits energy from a charging base station (transmitter) to a coil on a portable device (receiver) while maintaining complete galvanic isolation. The receiver coil converts the power of the electromagnetic field into electrical power. The purpose of This project is based on an electronic circuit that converts 230 volts at 50 hertz to 12 volts at high frequency. As the output, it is routed to a tuned coil forming circuit. An air core transformer's primary winding The secondary coil generates a high-frequency (12 volt) voltage. As a result, power is transferred from the primary (transmitter) to the secondary, despite the fact that they are separated by a significant distance (say 3cm). As a result, the transfer could be thought of as the primary transmitting and secondary receiving power to power the load.

Project Objectives

1) Wireless power transfer in the near field will be accomplished through resonant inductive coupling between the transmitting and receiving coils. The goal of wireless power is to demonstrate successful power transfer by lighting a light bulb. Over a distance, the device will be able to transmit maximum (W) power. To cancel harmonics and transfer the most power, a rectifying circuit will be used to charge a battery. The WPT system can effectively transmit power from the source to the device by using electromagnetic induction.

2) We pursued this project due to market constraints, as there is no such technology using a wireless electrical transfer power system available in Pakistan. Customers can transfer not only power, but also wireless electrical power or electromagnetic power. Wireless Power Transfer System (WPT). The system consists of a transmitting and receiving surface, both of which are made up of planar spiral coils. Two WPT systems (periodic and a periodic) with two coil types were investigated (circular and square). A periodic system's adjacent coils were wound in the opposite direction. The effect of coil type, winding direction, number of turns, and distance between coils on the efficiency of the shunt.

3) The proposed system was compared to a WPT system that can be used for simultaneous charging of many sensors (located in, for example, walls or floors). In periodic models, circular coils outperformed square coils in terms of efficiency. The results obtained using both proposed methods were consistent, confirming the correctness of the assumptions used. For a smaller radius of the coil in a periodic model.

Benefits of the Project

1) Allows for charging of multiple devices. This is achieved by changing the coil geometry, as well as allocating large charging surface areas such as table tops and charging benches.

2) High charging speeds: though at the moment wireless charging offers a slower charging rate than the wired option, advances in resonance and induction technology promises an increased charging rate and improved efficiency in the future

3) Wireless power transfer allows for greater spatial freedom between the power source and the device. This means that the two do not have to be precisely aligned for power transfer.

4) Eliminating charging cords enables engineers to make compact and watertight devices, thus maximising on safety, and varied use such as in deep-sea applications.

5) Prevents corrosion and sparking by eliminating mechanical connectors and wired contacts

6) Reduces costs associated with maintaining and replacing mechanical connectors

Technical Details of Final Deliverable

The main concept of this project is to design a device for the concept of wireless power transfer to eliminate the use conventional copper cables and also current carrying wires.

This project is built upon using a circuit which converts AC 230V 50Hz to AC 12V, High frequency (HF). The output is fed to a tuned coil shaping as main of an air core transformer. The minor coil develops a voltage of HF 12volt.

Thus the power transfer can be done by the primary to the secondary that is divided with 3cm distance. So the transfer could be seen as the primary transmits and the secondary receives the power to run a load.

In addition, this method can be used in several applications, like to charge gadgets like mobile phone, laptop battery, iPod, propeller clock wirelessly. And also this type of charging offers a far lower risk of electrical shock as it would be galvanically isolated.

This is an Emerging Technology, and in future, the distance of power transfer can be improved as the study across the world is still going on.
